Don't they know about your allergy? Of course they should have cleaned the house if they knew it would bother you!

They lock the cat out of the living room & kitchen for me.

I remember once babysitting my godson. He was playing on his playstation in the games room and asked me to join him and watch him play (ever since he played a zombie game on that playstation, he's a bit afraid to go to that room alone when it's dark outside ).
The cat had been sitting on that chair and the cat's hair was triggering an astma attack so I told the boy that I'm sorry but I couldn't sit in the room due to my cat allergy.

The boy said: "no no no...clean...me clean for you"
After which he started to clean the sofa thoroughly and he said that he would come and get me when it was safe to come back.

I actually did take my allergy pills since the cold weather triggers my skin allergy so I increased my medication (me and my damn allergies) but cat allergy is strong stuff.

During the summer, I spend some time in a friend's house in England and there's a cat in that house. So, I went to the doctor beforehand to prepare my body for the cat allergies. I didn't have a reaction but that requires heavy-duty medication which I'm not prepared to take all year long. I figured that sending the cat out of the room was enough.
